A Mission is in fact a moral contract: the one who accepts the Mission signs to accomplish the Mission objective, by respecting given conditions. The one who proposes the Mission signs to give the reward to the one who succeeds in the Mission.
A Mission is given by a bot or an other player.
We only care in this document about Missions given by bots; the ones given by players are managed by the player who proposes them, and the game doesn't interfere in this case, it's pure roleplay.
The one who proposes the Mission is a Missions giver; to give Missions is his/ her job, or more often this bot decides to propose a Mission after one or more events happen (friend death, recent gossip, etc).
Missions are time limited or not: after a certain date (duration or happening of a particular event (end of another Mission, etc)), the bot who has launched the Mission can decide it's cancelled (with or without informing questers), choose other questers in addition or replacement, send questers to kill or punish bad questers, etc.
